Breakups happen for reasons sometimes unknown and they are so very emotionally painful, sometimes it can leave someone feeling broken and dead inside and most people think that when it happens all the people want to talk about is the breakup, but let me tell you, THAT IS NOT THE CASE!
Talking about it is painful and it makes the person cry so whatever you do, DON'T bring it up.
When it first happens, people often want to talk about it because they want to make sense of what just happened, but after a day of people constantly asking or offering condolences, it just gets tiring and brings up unnecessary emotions and isn't really good.
Being alone for a day or two is also really helpful, but the transition into normal social environment becomes difficult because you have those people who don't understand what you're going through.It's really mourning the death of a relationship and like regular deaths no one truly understands what you're going through even though they have gone through it before no one can understand what your feelings are.
Hanging out with friends or family helps more than people think, but also it hurts so you have to find a balance between friends and family and being alone.
But past is the past and once that is accepted one can truly move towards the future.
